m-CPBA/KOH: An Efficient Reagent for Nucleophilic Epoxidation of gem-Deactivated Olefins
摘要:
The m-chloroperoxybenzoate anion (generated from m-CPBA and bases such as K2CO3 or KOH) is a highly efficient nucleophilic epoxidating reagent for strongly deactivated olefins containing two electron-withdrawing groups at the same carbon, under mild conditions which affect neither other double bonds nor electrophilic oxidizable centers such as sulfoxides.
